Brian S. Whalen CPA

Tattooed and occasionally cursing like a sailor (he was a sailor in the Nuclear Navy), Brian is not your typical CPA. He has no problem serving Cannabis Entrepreneurs; it’s his calling. Corporate America’s competitive advantage lies within their finance and accounting functions. Green Bean CFO was founded to level the playing field for established cannabis businesses and newcomers alike by providing an affordable finance/accounting department.
